Key filtration features
The filter combines a high-efficiency particulate air (HEPA) media with a robust activated carbon layer. This dual-layer approach supports capturing fine particles such as dust, pollen, and pet dander, while the carbon layer helps address common household odors from cooking, smoke, and pets. The media is engineered to tackle particles around 0.3 microns with high efficacy, contributing to a sense of fresher air through the purifier.
